... Back strap in #3 position (it won't go back to #4 without a long screw which I don't have to put the strap on the bump). Front strap was in #2 position. So for today's trial I slide it back to the number #4 position (all the way back).
... This may be a limitation of the dwarf craft? Not enough range in the mast track?
... my back leg was still pretty loaded
it is a limitation of nearly all boards, even those of Groove who are the only ones using longer tracks with 10 cm of movability (for 16,5 cm plate). For all my foils I would require up to 20 cm, so 35 cm long tracks. But you can improve your strap position significantly:
First, NEVER use a longer screw for the hole under the tail bump, as if once entered you may start to screw it more and more down when the pump gets pressed together and then invisibly crash the plug -> Water in the board.
Try to press the pump down as hard and as long till it stays there (can be effort, use wood log, board upside down but carefully to not overload) or cut the bump away (unfortunately just GONG builds boards with a cut out bump).
If you additionally turn around the strap for the back screw you may get around 6 cm extra backwards foot placing, as shown:
Otherwise you just can rise negative angle of attack of the stabi or take a bigger one, to get your pressure point towards front foot, but this will also rise drag, so wouln't be my favour.
